Network Warrior takes you step by step through the world of hubs, switches, firewalls, and more, including ways to troubleshoot a congested network, and when to upgrade and why. Along the way, you 'll gain an historical perspective of various networking features, such as the way Ethernet evolved. Based on the author 's own experience as well as those he worked for and with, Network Warrior is a Cisco-centric book, focused primarily on the TCP/IP protocol and Ethernet networks -- the realm that Cisco Systems now dominates. The book covers:
The type of networks now in use, from LANs, WANs and MANs to CANs
The OSI Model and the layers involved in sending dataHubs, repeaters, switches, and trunks in practiceAuto negotiation and why it 's a common problem in network slowdownsRoute maps, routing protocols, and switching algorithms in Cisco routersThe resilient Ethernet -- how to make things truly redundantCisco 6500 multi-layer switches and the Catalyst 3750 switchTelecom nomenclature -- why it 's different from the data worldT1 and DS3Firewall theory, designing access lists, authentication in Cisco devicesServer load balancing technologyContent switch module in actionDesigning QOS and what QOS does not doIP design and subnetting made easy
The book also explains how to sell your ideas to management, how networks become a mess as a company grows, and why change control is your friend. Network Warrior will help network administrators and engineers win the complex battles they face every day.
Anyone with a CCNA or equivalent knowledge will benefit from this book, especially entrenched administrators, engineers, or architects tasked with building an Arista network. Is Arista right for your data center? Pick up this guide and find out.
Topic highlights include:SysDB: the EOS system database that holds state, statuses, and variablesMultichassis Link Aggregation (MLAG): for linking a port-channel to multiple switches instead of just oneLatency Analyzer (LANZ): the interface-buffer troubleshooting tool with a reporting granularity of one millisecondVM Tracer: for adding, changing, and removing VLANs without human interactionZero-Touch Provisioning (ZTP): for remote switch configurationHardware advantages: including merchant silicon, low-latency networking, and power consumptionGotchas: issues with Arista switches or systems
